Helicobacter pylori and idiopathic chronic urticaria

BACKGROUND: Different studies have shown a high prevalence of Helicobacter pylori (HP) infection in patients with chronic urticaria (CU), and occasional remission of the skin lesions after eradication therapy. Recent investigations, however, have failed to find a significant relationship between the two conditions. We designed a case-control study to assess the prevalence of HP infection and the effect of bacterium eradication on the outcome of the skin disease in patients affected by CU. The literature is reviewed. METHODS: Twenty-five patients diagnosed with CU were included. Information about their medical history and a complete laboratory investigation ruled out other diseases or situations suspected to cause CU. Twenty-five healthy volunteers from a census-based, randomized sample were used as controls. HP infection was assessed by the (13)C-urea breath test (UBT). Eradication therapy included oral amoxicillin, omeprazole, and clarithromycin for 1 week. RESULTS: The high prevalence of HP infection (68%) and mean titer of UBT (24.13) in our patients with idiopathic CU do not differ from the general population. Marked differences were observed in the mean age of the CU patients with positive UBT (45.52years) vs. those without HP infection (35.25 years). After eradication therapy, only one patient showed a complete remission of urticaria and two showed a partial remission. CONCLUSIONS: Our results support a lack of relationship between HP infection and the course of idiopathic CU.     

The relationship between Helicobacter pylori IgG antibody and autologous serum test in chronic urticaria

BACKGROUND: In chronic urticaria, suspicious factors are Helicobacter pylori (HP) infection and autoimmunity, as well as other etiologic agents. Autologous serum injection is the first step to identify autoimmune urticaria. Our study was performed to determine the prevalence of HP infection in patients with chronic urticaria, and to evaluate the results of autologous serum testing in chronic urticaria patients who had HP antibodies. METHODS: HP immunoglobulin G (IgG) antibody was defined by an immunochromatographic method in 61 chronic urticaria patients and 15 healthy persons. Autologous serum testing was performed in 32 chronic urticaria patients. RESULTS: HP IgG antibody was found to be positive in 41% of chronic urticaria patients and 26% of healthy controls (chi2= 7.82, P= 0.005). Autologous serum testing was positive in 40% of chronic urticaria patients who had HP IgG antibody. This ratio was 14.3% in chronic urticaria patients who did not have HP IgG antibody (chi2 = 9.23, P= 0.002). CONCLUSIONS: In this study, autologous serum testing was found to highly positive in chronic urticaria patients with HP IgG antibody, but the relationship between autoimmunity and HP infection requires further investigations.     

Prevalence and relevance of the positivity of skin prick testing in patients with chronic urticaria

Many patients with chronic urticaria (CU) worry that foods or other allergens are responsible for their urticaria. Skin prick testing (SPT) may be one of the investigations used to provide a clear illustration. The purpose of our study was to assess the prevalence of positivity of SPT to food allergens and aeroallergens and their relevance in patients with CU, in order to demonstrate the diagnostic value of SPT in CU. We retrospectively reviewed case record forms of patients with chronic ordinary urticaria who underwent SPT in the Urticaria Clinic, Siriraj Hospital, during the period 2000-2004. The studied allergens included 16 food allergens and 12 aeroallergens. Eighty-eight patients were enrolled. The prevalence of positive SPT among patients with CU was 47.7%. Patients who had personal histories of atopy had statistically significant positive SPT results compared with patients who had negative SPT. Of 88 patients, 26 patients (30%) gave positive results to food allergens, 36 patients (41%) gave positive results to aeroallergens and 20 patients (22.7%) gave positive results to both food and aeroallergens. One-third of the subjects (34.6%) who had positive SPT results to food allergens had clinical relevance of food allergy in some systems but only one patient had clinical relevance of food-induced urticaria. Half of the patients who had a history of aeroallergen sensitivity gave a positive SPT response for aeroallergens; however, there was no clinical relevance to their CU. Our study showed that the prevalence of positive SPT to food allergens and aeroallergens in patients with CU was common but had little clinical relevance to CU.     

慢性荨麻疹患者血清抗幽门螺杆菌抗体的检测及意义

为探讨幽门螺杆菌感染在慢性荨麻疹中的作用，作者采用间接ＥＬＩＳＡ技术检测了２６例生荨麻疹患者的血清抗Ｈｐ抗体。结果显示：２６例慢性荨麻疹患者中有１７例血清抗Ｈｐ ＩｇＧ抗体阳性，应用根除Ｈｐ感染的方案治疗２月后，１７例阳性患者有１２例获得痊愈。由此考虑Ｈｐ感染可能与部分荨麻疹的发生有关。     

慢性荨麻疹患者粉尘螨变应原皮肤点刺反应与自体血清皮肤反应的关系

Chronic idiopathic urticaria: prevalence and clinical course

The purpose of our study was to assess the prevalence and clinical course of patients with chronic idiopathic urticaria (CIU), as well as possible causes or associated findings, laboratory findings and the duration of the disease in patients with chronic urticaria (CU). We retrospectively reviewed the 450 case record forms of patients with CU and/or angioedema who attended the Department of Dermatology, Siriraj Hospital, during the period 2000-2004. Of 450 patients with CU, 337 patients (75%) were diagnosed as CIU. Forty-three patients (9.5%) had physical urticaria, while 17 patients (3.8%) had infectious causes. Other possible causes were food, thyroid diseases, atopy, drugs, dyspepsia and collagen vascular diseases. In eighty-nine percent of patients, no abnormalities were detected at the time of physical examination. The most common abnormal laboratory finding was minimal elevation of the erythrocyte sedimentary rate (42%). In 61 patients, autologous serum skin tests had been done. Fifteen patients (24.5%) had positive results i.e. autoimmune urticaria. Anti-thyroglobulin and anti-microsomal antibodies were positive in 16 % and 12% of CIU patients respectively. After 1 year from the onset of the symptoms, 34.5% of CIU patients were free of symptoms and after 1.2 years from the onset of the symptoms, 56.5% of autoimmune urticaria patients were free of symptoms. The median disease duration of CIU and autoimmune urticaria were 390 days and 450 days respectively. Our study provided an overview of CU and CIU in a large series of Thai patients, based on etiological aspects and clinical courses.     

Chronic urticaria is associated with a differential helminth-arthropod-related atopy phenotype

The relationship between atopic sensitization and chronic urticaria is still controversial. In this study, we aimed to compare the prevalence of aeroallergen sensitization in chronic urticaria patients with (CU/As+) and without (CU/As-) sensitization against Anisakis simplex. Forty-nine CU/As+ and 80 CU/As- patients were studied and skin prick tests (SPT) were performed against aeroallergens. We assessed sensitization in a subgroup of patients with allergic rhinoconjunctivitis and/or bronchial asthma (RCBA) and compared the prevalence with a control group of 522 non-urticaria patients with RCBA. Forty-five percent of CU/As- and 60.4% of CU/As+ patients displayed positive SPT to at least one aeroallergen. CU/As+ patients had a higher prevalence of sensitization against pollen, mould or dander (PMD) (52.2% vs 29.1%, P < 0.01), whereas the prevalence of house dust mite (HDM) sensitization was not statistically different (26.3% in CU/As- and 36.7% in CU/As+). However, in chronic urticaria patients with RCBA, 53.8% of CU/As- and 57.9% of CU/As+ patients differed in the prevalence of HDM sensitization compared to the control group (33.5%, P = 0.03), whereas no difference could be stated for PMD sensitization. Compared to RCBA patients, both CU/As+ and CU/As- patients have a higher clinically relevant sensitization rate against HDM, thus displaying a differential atopy phenotype.     

Increased levels of serum IL‐31 in chronic spontaneous urticaria*

Please cite this paper as: Increased levels of serum IL‐31 in chronic spontaneous urticaria. Experimental Dermatology 2010; 19: 464–466. Abstract: IL‐31 represents a novel cytokine involved in pruritic skin diseases including atopic dermatitis (AD). We, therefore, aimed at investigating IL‐31 levels in chronic spontaneous urticaria (CU). We included 46 patients with CU, 26 non‐atopic skin healthy subjects as negative and 28 patients with AD as positive controls. IL‐31 serum levels were analysed using commercial ELISA kit. IL‐31 serum levels were higher in patients with CU compared to healthy controls (P < 0.001), but lower compared to patients with AD (P < 0.001). There was no difference in IL‐31 serum levels in autologous serum skin test positive or negative CU patients and patients with infectious trigger factors including helicobacter pylori infection. IL‐31 serum levels may play a role in the pathophysiology of CU. This is supported by the finding that not all patients with CU respond to antihistamine treatment but to the treatment with immunosuppressive drugs.

Chronic urticaria and osteoporosis: a longitudinal,community-based cohort study of 11 944 patients

Osteoporosis is a condition in which the bones are thinner and more liable to fracture. It is commoner in women and in people over 50. It cannot be cured so the focus is on prevention, which means identifying and addressing risk factors such as obesity, low vitamin D, chronic inflammation and prolonged steroid medication. Chronic urticaria (hives, CU) is an inflammatory condition, so one might expect it to be linked with osteoporosis, but that has never been investigated. If people with CU are indeed more likely to develop osteoporosis, they could be advised about preventative measures. To study this, doctors from Israel identified 11,944 patients diagnosed with CU in a large medical database covering 4.5 million people. A potential difficulty was that people with CU are more likely to be female, obese and to have been treated with systemic steroids, all of which also increase the risk of osteoporosis. Therefore for each CU patient they studied 5 age- and sex-matched control patients (people of the same age and sex but without CU) and their analyses took into account other known risk factors for osteoporosis. During a 16 year period 8.7% of the patients with CU were diagnosed with osteoporosis compared with 6.8% of the controls. They concluded that CU is a small but significant additional risk factor for osteoporosis. An accompanying editorial cautions against basing conclusions on routine health records which may not have all the information required. Nonetheless, doctors treating chronic urticaria might bear in mind the risk of osteoporosis in their patients, and counsel accordingly.
